hi,

Sure, you can map your filter on to /* or something like that. That way you
can intercept any URL you like and either rewrite, or redirect.
It doesn't matter if your URL reads /something/something/default.asp or not,
if you know how to handle that url from your filter (usually done by reading
config from file or database). If you are using mod_jk then you might have
to change your mapping in to tomcat.

I've been implementing this by using filters for a long time, never had
problems with it.

hope it helps
